Carbon filter adapter for Ikea UPPATVIND

Carbon filter adapter for Ikea UPPATVIND

I'm using this cheap Ikea UPPATVIND air purifier in 3d printer enclosure.

 Air purifier lacks carbon filter, I have added adapter that I can use custom one. 

Tested filament: petg

Parts (minimum): 2xprofiles, 4xribs

Printing: could be 16 shells, no infill, no top layers, no bottom layers,

Assembling: connect all parts

Mounting: I start with top, then stretch adapter so it can fit in bottom.
